SILK AND THREAD POLISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 281,705, dated July.24, 1883.

- Application filed January 5, 1883. (N0 model.)

I0 aLL wltom Z5 may concern:

Be it known that I, WILLIAM R. LANDFEAR, of the city of Brooklyn, in thecounty of Kings and State of New York, have invented a new and usefulImprovement in Silk and Thread Polishing Machines, of which thefollowing is a specification.

My invention relates to that class of silk and thread polishingmachinery in which the silk or thread is wound one or more turns aroundeach of a series of cones, which are supported on pivots, so that theyare free to rotate, and which are rotated rapidly as the silk or threadis drawn forward and wound upon spools. In such machines the cleaning orpolishing is effected by the rubbing of the silk or thread on itself asit passes around the cones.

The principal object of my invention is to provide a machine forcleaning and polishing thread or silk very thoroughly and rapidly; andmy invention therefore consists in various novel details of constructionand combinations of parts in machines of that class, hereinafterdescribed and claimed.

The several features of my invention are illustrated in the accompanyingdrawings, in

which Figure 1 represents a side elevation of a machine embodying myinvention. Fig.2

represents a plan thereof. Fig. 3 'represents an end elevation thereof.Fig. 4. represents a detail sectional view upon alarger scale, showingthe construction and relative arrangement of the cones and theirbearings; and Fig. 5

represents a plan of the cone and a portion of one of the rails wherebythe cones are supported.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the end frames of the machine, which are connected bystretchers or longitudinal rails A.

B designates the driving or main shaft, which is here shown as having atone end fast and loose pulleys B 13 for the reception of a driving-belt,and at the other end a bevelwheel, a, gearing into a second wheel, a, onan upright shaft, 0.

D designates a carriage, supported at opposite ends by vertical rods D,which are fitted to bearings or guides]; in such manner that they andthe carriage are free to move vertically. Each of the rods D is providedwith a fixed sleeve or collar, 1), on which is a pin or roller, b, andsaid pins or rollers rest upon and are acted upon by cams c, placed onenear each end of a shaft, E, extending from end to end of the machine.The shaft E carries at one end a worm-wheel, d, which engages with andreceives motion from a worm or screw, (1, upon the upright shaft C. Theshaft E is thereby rotated slowly, compared with the shaft 0, and as itrotates its cams c act upon the pins or rollers b and impart to thecarriage D the rising-and-falling movement nec- 'essary for atraverse.

The carriage D carries a number of spindles,

e, on which are placed spools e, and to which are secured whirls e Thesespindles are here arranged in two rows, as best shown in Fig. 2, thespindles in each row being opposite the spaces in the other row. In Fig.1 only a few of the spindles are shown entire, and of the others onlythe lower portions and the whirls are shown. The spindles are allrotated by a single belt or band, C, which passes around and receivesmotion from adrum or pulley,

G on the upright shaft 0, as best shown in Fig. 1. In Fig. 2 I haverepresented the upper board or portion of the carriage D as removed fora part of its length, so as to show the driving-band C in its passagearound the spindles in the two rows.

At the opposite sides of the machine are horizontally-extending boardsF, carrying skewers or pins f, on which are placed spools or bobbins f,from which the threads or silk is conducted to the spools e. The threador silk, in its passage from each spool or bobbin f, is carried to orthrough a tension device, G, here shown as consisting of a smallcylinder or tube around which the thread or silk is wound one or moretimes, and which has a hole or opening in its head or end through whichthe thread or silk is carried. I make 9* no claim to this particularform of tension device, and in lieu thereof a tension device of anyother form may be employed.

The cleaning or polishing of the thread or silk is performed between thetension device G and the spools 0,and I will now describe the meansemployed for the purpose.

Extending transversely to the rails A, and in line with each spool f andits opposite spool, c, is a bar or rail, H, which in reality pivot, 71,which fits in a tube, 1, securedin the socket by a set-screw, j. Thetubei forms a bearing for the pivot 71, and as the cone I is hollow saidtube can extend up into it nearly to its end.

Upon the rail H and adjacent to each socket are projections or ribs 8,which project beyond the lower edge of the cones, on opposite sidesthereof, and prevent the thread or silk from getting around thebearing-tube i below the cone. As here shown, the cones I in each row oneach rail H are all arranged with their axes in the same inclined plane,and the axes of the cones in each row are inclined at a reverse angle tothe axes of the cones in the opposite row. The thread or silk, as itrapidly winds 011 and unwinds from the cones l, rubs and ehafes onitself, and is thereby cleaned and polished, and the arrangement of thecones at reverse angles effects the cleaning and polishing of the threador silk all round, and preserves it in its round form.

W hat I claim as my invention, and desire to secure by Letters Patent,is

1. The combination, withaspindle-carriage, mechanism for imparting arising-and-falling motion. thereto, spindles in said carriage, and meansfor rotating them, of bars orwra-ils arranged transversely to the lengthof said earriage, and series of loosely-pivoted cones carried by saidbars or rails, and around which the thread or silk is to be wound in itspassage to said spindles, substantially as and for the purpose hereindescribed.

2. The combination, with a spimlle-earriage, mechanism for imparting arisingand-ialling motion thereto, spindles in said carriage, and meansfor rotating them, of bars or rails arranged transversely to the lengthof said carriage, and two rows of loosely-pivoted cones carried by eachbar or rail, the cones in the two rows being arranged with their axes atangles to each other, substantially as and for the purpose hereindescribed.

3. The combination of the carriage 1), the shaft E, and devices actuatedthereby forgiving said carriage its rising-and-falling move ment, thespindles 0, provided with whirls c", with the vertical shaft 0, the drum0, and band or belt C, mechanism for rotating the shafts C and E, thetension devices G, the rails H, and loosely-pivoted cones I,substantially as and for the purpose herein described.
